Overview
Overview
A rugged portable multi gas detector with a compact and affordable design meant to withstand harsh environments. Developed with User-Centered Design Process to make the device interface and handling highly intuitive. The bright color LCD display with loud alarms and vibrations is helpful in a noisy environment. The rugged anti-static exterior provides accurate reading even when exposed to temperatures ranging from -20°C to +60°C and humidity ~95% RH.
The small and lightweight package can host up to 4 gas sensors. The standard 4 gas combination includes CO, H2S, Methane, and O2. The other gases supported being NO2, SO2, CL2, NH3, and many more.
It is designed and tested to meet global IS standards, ensuring safe operations in hazardous environments.
